LyX ⇒ SIGSEGV signal caught

[brenogil]

Hello everyone!

(sorry if this topic is repeated)

I have installed LyX in two of my computers and in both it crashes when I run a spell check and ask it to replace a misspelled word.

The crash message is attached.

Any Idea what is going on?

Thank you,

[Stefan Kottwitz]

Hello brenogil,

welcome to the board!

If you did not install the newest one, version 2.0.4, I recommend to install that. If the newest one crashes, perhaps an older stable version would work for you.

Stefan's advice is spot on (as always!). I just wanted to follow up. Did you solve the problem by installing a newer version? What OS are you using on both of the computers? Which LyX versions?

There are a couple of people reporting problems similar to what you describe:

Hi there,

I've got this same error a few times in the past few days. I'm running the most recent version of LyX (2.0.5.1) on a Mac. It seems to happen for no particular reason. The last time it happened when I exited Fullscreen view, but earlier it was for different reasons.

Has anyone else had this problem with this version?
And can anyone recommend me a more stable earlier version?

Thanks very much.

I've actually just had a repeat of the SIGSEGV crash which happened again as I was exiting Fullscreen mode. Anyone else experiencing this?

Strange -- I've never heard of that. If you know how to use gdb and can provide a backtrace, we can probably figure out the problem. If not, there's not much we can do unless you write steps that are able to reproduce the problem.

I've just had the same crash when exiting Fullscreen. I'm not sure if this will help, but here's the Apple crash report (I don't know how to use gdb, sorry):

Yes, that is useful. Can you post that and a description of the problem on a new bug report?
http://www.lyx.org/trac
Also mention whether it happens every time you exit full screen or only sometimes.

And put whether this is on 2.0.5.1.

Thanks,

Scott

Thanks! Hopefully someone can reproduce the problem and figure out what's going on.
